BLOCK-REFINISHER.

Specification of Letters Patent.

Application filed J \111720, 1914:. fierial No. 851,895.

7 '0 all whom it may concern:

Be it known that we, FRANK J. PAvELs E and FELIX F. MALODZIK, both citizens of the United States, and residents of Cudahy, 1n

' the countyof Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Block-Refinishers'; we do hereby declare that the following 1s .a full, clear, and exact description thereof.

Theobject of ouroi nvention is to provide a simple, economical and efiective apparatus for refinishing the surfaces of butchers" blocks, the same being so constructed and arranged that a table is adjusted to one side of the block upon the desired plane of the cut for initially supporting a self-contained motor driven cutter, the cutting face of the tool being upon the plane of the upper surface of'the table, whereby the motor which is arranged to float or slide upon the table can be shifted therefrom to the refinished surface-of the block, which refinished surbodying the features'of ourinvention, the

same being shown partly in section, as indicated byline 11 of Fig. 2 and attached to a block to be refinished; Fig. 2, a sectional plan View of the same, the section being indicated by line 2-2 of Fig. 1, and Fig. 3, an end View of the table mechanism with parts in section as indicated by line 33 of Fig. 1.

Referring by characters to the drawings, 1 represents a table which is, as shown, adapted to have oneedge arran ed inabuttmg engagement with the bloc to be refinished, the upper surface of said table being adjusted upon the line of cut, as indicated. The table is provided with transversely disposed slotted ears 2, which ears project beyond the juxtaposed edges of said table and the slots thereof are arranged to receive draw bolts 3 provided with wing nuts 3, whereby the drawbolts are tights ened. The inner hooked ends of the drawbolts have connected thereto chain or cable stretches 4, the opposite ends of which stretches are adjustably connected .to the hooked :ends of drawbolts'5. These drawbolts are carried by .a transversely disposed clamping bar 6, which bar is formed from two members bolted together and spaced apart to provide a coptinuous slot 6 through which the threaded shanks of the drawbolts 5 extend, the same being confined by thumbnuts 5'. With this slotted arrangement of the draw-bar 6 and ears .2 which are connected to the table, the apparatus may be adjusted to diflerent widths of blocks, it being understood that when either set of drawbolts are tightened that the connecting chain stretches will thus securely clamp the inner edge 00 of the table to the juxtaposed edge of the butchers block. In order to provide a vertical support for the inner edge :0 of the table, its lower face has secured thereto a pair of depending ears 7, which ears carry pointed ended set-screws 7 the same constituting pins, the points of which are embedded into the block. Thus the inner edge of the table is held against dropping downward under strain. The outer edge 3 of the table is supported by a leg 8, which leg is secured to a post 9 by a clamping bolt 10 that extends through the post and through the slottedv shank 8 of the leg, the said bolt being) held by a binding nut 10'. Hence it will. e seen thatthe leg may be adjusted as to length vertically to accommodate elevation of the tableand to also finelv adjust the upper surface of said table whereby it is maintained upon a horizontal plane, which plane constitutes a gage for the depth of cut in a refinishing operation of the block.

Owing to the fact that it is important-to provide a fine adjustment for the upper-surface of the table in order that it will assume a true horizontal plane and also to insure rigidity of the table 'in connection with the block, we provide .the under surface of said table with depending bracket arms 111. These arms carry adjusting thumb screws 12 having feet 12' that engage the adjacent vertical surface ofthe block and by a slight manipulation of'the thumb screws it is ob- .vious that the. upper surface of the table ment the pins 7' form fulcrum points. After i the fine adjustment just mentioned has been effected, the table leg'8 is drop ,ed to a position of engagement with the oer-line and thereafter firmly secured to the post by ma the lower ends of which are roundedto form sliding supporting feet for the motor, where by the latter may be manipulated back and forth at the will of the operator, the said motor being provided with hand grips b to facilitate such manipulation. Hence it will be seen that the motor may be slid back and forth upon the table in any direction.

' The studs 13 are independently adjustable and form a three point contact, being held in their adjusted positions by set nuts 13. This adjustment of the studs which constitute feet for the motor is for the purpose of alining the cutting surface of a cutting tool 14 withthe face of the table 1, it being important that this alinement is true in order that the tool, when effecting a refinishing operation,will true off the surface of the block upon the same plane as the surface of the table, whereby the'refinished surface of said block will form a continuous ground upon which the feet of the motor may travel after the initial refinishing operation. Hence the cutting tool is advanced and refinishes the block upon the same plane as the surface of the table. The cutting tool, as shown in Fig. 1, is detachably secured to a drivenspindle 15, which spindle is revolubly mounted in suitable bearings that extend from the head of the motor, the said spindle being in miter gear connection with the motor shaft.

It should be understood that after the entire surface of the'block has been refinished in alinement with the surface of the motorsupporting table, the rotary cutting tool may From the foregoing description it is ap parent that after the apparatus has been adjusted to a block, as shown, the operator can readily shift the cutting tool carried by the motor back and forth upon the table until such time as the surface of the block adjacent to the table is removed or finished and, as the work progresses the operator shifts the motor from the table to the block which now forms a support. Thus the feet of the motor traveling over the finished block will at all time gage the depth of cut and when the block has been entirely refinished its surface will be upon the plane of the surface of the table.

We claim:

1. A block refinishing apparatus comprising a horizontally'disposed table, means for attaching the same to one edge of the block,

means for adjusting the table relative to the face of the block for gaging the depth of out in arefinishing operation, a floating motor having supportln feet adapted to mitially rest upon the ta lo, a cutting tool carried by the motor,- the cutting face of which is disposed upon the same plane as the upper surface of the table, whereby the block is initially resurfaced to form a continuation of the table surface to permit the motor to travel from said table onto the block.

2. A block refinishing apparatus comprising a horizontally disposed table, means for attaching the same to one edge of the block, means for adjusting the table relative to the face of the block for gaging the depth of out in a refinishing operation, a floating motor onto the block.

In testimony that we claim the foregoing we have hereunto set our hands at Milwaukee in the county of Milwaukee and State of Wisconsin in the presence of two witnesses.-
